Zusammenfassung:	To reduce the radial stress on a stator.SOLUTION: A rotating electrical machine unit (100) includes a casing (20), a rotating electrical machine (30), a support (23) that supports a stator (31) of the rotating electrical machine (30), and a fluid passage (C) that cools the stator (31) of the rotating electrical machine (30). The fluid passage (C) includes a first gap (34) formed between the outer peripheral surface of the stator (31) and the inner peripheral surface of the casing (20). The first gap (34) includes a first space (34a) formed continuously around substantially the entire circumference of the stator (31). An axial end face of the stator (31) is fixed to the support portion (23).SELECTED DRAWING: Figure 5 【課題】固定子の径方向に生じる応力を低減する。【解決手段】回転電気機械ユニット（100）は、ケーシング（20）と、回転電気機械（30）と、回転電気機械（30）の固定子（31）を支持する支持部（23）と、回転電気機械（30）の固定子（31）を冷却する流体通路（C）とを備える。流体通路（C）は、固定子（31）の外周面とケーシング（20）の内周面との間に形成される第１隙間（34）を含む。第１隙間（34）は、固定子（31）の略全周に連続して形成される第１空間（34a）を含む。支持部（23）には、前記固定子（31）の軸方向の端面が固定される。【選択図】図５
